Privy

Privy is a simple toolkit for progressive authentication in web3. With a single library, you can easily onboard both expert users and newcomers alike, through Privy's powerful wallet connectors and delightful embedded wallets.

Privy makes it easy to integrate every major wallet into your app without having to wrangle the connectors individually. You can check out Privy in action here.

Privy comes pre-packaged with Phantom so you can support your Phantom users right out of the box. Here’s how.

Prerequisites

The Privy React Auth SDK allows you to authenticate your users with Privy in your React app in minutes. You can follow the standard guide here.

Building a new app? Check out these starter templates for integrating Privy into:

a NextJS project (GitHub, CodeSandbox)
a Create React App project (GitHub, CodeSandbox)

1. Get a Privy account

Request access to Privy and get keys in minutes. Retrieve your Privy app ID from the developer console at console.privy.io

2. Install the Privy npm package

Install the Privy React Auth SDK using npm:

npm install @privy-io/react-auth

3. Configure Privy

Once you have your app ID, in your React project, wrap your components with a PrivyProvider. The PrivyProvider should wrap any component that will use the Privy SDK.

If you're starting from scratch, we recommend using one of these templates to integrate Privy:

a NextJS project (GitHub, CodeSandbox)
a Create React App project (GitHub, CodeSandbox)

For example, in a NextJS or Create React App project, you may wrap your components like so:

import type {AppProps} from 'next/app';
import Head from 'next/head';
import {PrivyProvider} from '@privy-io/react-auth';

// This method will be passed to the PrivyProvider as a callback
// that runs after successful login.
const handleLogin = (user) => {
  console.log(`User ${user.id} logged in!`)
}

function MyApp({Component, pageProps}: AppProps) {
  return (
    <>
      <Head>
        {/* Edit your HTML header */}
      </Head>
      <PrivyProvider
        appId={process.env.NEXT_PUBLIC_PRIVY_APP_ID}
        onSuccess={handleLogin}
      >
        <Component {...pageProps} />
      </PrivyProvider>
    </>
  );
}

import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import reportWebVitals from './reportWebVitals';
import {PrivyProvider} from '@privy-io/react-auth';

const root = ReactDOM.createRoot(document.getElementById('root'));

// This method will be passed to the PrivyProvider as a callback
// that runs after successful login.
const handleLogin = (user) => {
  console.log(`User ${user.id} logged in!`)
}

root.render(
  <React.StrictMode>
    <PrivyProvider
      appId={process.env.REACT_APP_PRIVY_APP_ID}
      onSuccess={handleLogin}
    >
      <App />
    </PrivyProvider>
  </React.StrictMode>
);

// See https://docs.privy.io/guide/troubleshooting/webpack for how to handle
// common build issues with web3 projects bootstrapped with Create React App

The PrivyProvider takes the following properties:

your appId
an optional onSuccess callback which will execute once a user successfully logs in
an optional config property to customize the look and feel of the Privy modal to match your app
